According to CBS Detroit, federal agents are digging up a field in Northern Oakland Township near the city in search for body of the former Teamsters boss.

"It's my fondest hope that we can give ... closure not just to the Hoffa family, but also to the community and stop tearing that scab off with every new lead and bring some conclusion," Oakland County Sheriff Michael Bouchard told the Detroit Free-Press.

The latest clue into the location of the Hoffa remains comes after Tony Zerilli, a former second-in-command with the Detroit mafia, told WDIV-TV that Hoffa was buried on that property. The Northern Oakland home was supposed to be a temporary residence until he was moved to a hunting lodge further upstate.

As CNN notes, the then- 62-year-old Hoffa disappeared outside a Detroit-area restaurant in 1975. The FBI believes that the mob could have something to do with his disappearance, as the criminals had great influence over the Teamsters' pensions at the time. Per My Fox Detroit, Hoffa's remains were never found, though he was declared legally dead in 1982.

Tony Zerilli first told reporters about the location of Hoffa's remains earlier this year. However, the FBI needed time to investigate the validity of these claims first before getting permission to dig.

Still, as Huffington Post notes, there are reasons to doubt Tony Zerilli's story. He was apparently in jail when Hoffa was allegedly murdered. He also is writing a book and thus might be lying about Hoffa's remains in order to garner some more publicity.

"I'd like to just prove to everybody that I'm not crazy," Zerilli told NBC New York earlier this year. "And it means a lot to me. What happened, happened while I was in jail. And I feel very, very bad about it and it should never have happened to Jim Hoffa. He didn't deserve what happened to him."

Until Hoffa's remains are found, plenty of rumors will continue to persist about the Teamsters boss' disappearance. Per Associated Press, some believe he was buried at the old Giants Stadium in New Jersey, which was recently torn down. Another theory places him somewhere in a Florida swamp. However, many believe he is buried somewhere near Detroit. The FBI has previously searched a horse farm and an outdoor pool in the area in an attempt to find Hoffa's remains.
